Doing the estimates is not the slow part. The slow part is backing up
filesystems than have not changed. The estimates take only about 15
minutes of the 10 hours of the backup. The tape drive spool up time
for 500 filesystems is most of the time.
Amanda is responsible for determining what filesystems get dumped to
tape. If a filesystem has not changed why does amanda still dump it?
